Eheim everyday feeders

Just got 8 more for $95 delivered! And no my source doesn't
have anymore and when he does I'm buying them too.

They now have a mounting bracket. My previous one didn't 
have this or were missing on my after market purchases.

Fits my plywood Ranchu tubs just barely.

Guide to Using Drugs, Biologics, and Other Chemicals in Aquaculture

The American Fisheries Society - Fish Culture Section's Working Group on Aquaculture Drugs, Chemicals, and Biologics (WGADCB) is proud to announce its publication of the Guide to Using Drugs, Biologics and Other Chemicals in Aquaculture and a companion tool to assist in the calculation of the amount of drug, biologic or chemical to be used for your specific aquatic animal treatment needs.The Guide is being published exclusively in electronic form to facilitate efficient and timely updates in our ever-changing regulatory climate.
The Guide is provided as an Adobe PDF file, requiring you to have Adobe Reader installed on your computer. Click here to install the latest version of the free Adobe Reader.
The Treatment Calculator is offered as a Microsoft Excel file. Your computer must have installed either Microsoft Excel or any other program that will read and execute calculations of an Excel file.
Note: At this time the available version of the Treatment Calculator can only be read by Excel 2007 or newer. An Excel 97-2003 compatible version is not currently available, but is being developed.

Drop your dream pin in the map

Saw this place in an aquaculture trade journal. 162 acre goldfish farm in the central valley of California. $3,000,000 a year sales when operational. You know what they say... How do you make a small fortune in aquaculture? Start with a large one.

DIY UV Servicing

Time to change the bulbs and clean the sleeves. This is a 130 watt (2x 65 watt) I made out of PVC parts. It runs the main central goldfish system.

Thin Film Surface Skimming Adjustable Standpipe

The Thin Film Surface Skimming Adjustable Standpipe has a one inch standpipe core and a two inch exterior that can slide up and down on the core to make fine adjustments. It is made with a 2 x 1 inch bushings with the stop ground out so it can slide up and down on the one inch standpipe for fine tuning. The bushing is inserted into a two inch coupling. The other end of the coupling has a 4 inch length of 2 inch pipe which becomes the top of the surface skimmer. To prevent fish from going over the standpipe a one inch bulkhead intake screen is inserted into a one inch couple or cap, inverted and inserted into the schedule 200 one inch stand pipe. This creates a 1/8 to 1/4 inch continuous gap between the one inch coupling and two inch pipe. This provides great thin film skimming.

Surface skimming is the most effective and simple way to remove the oily film of proteins and oils that build up on the water surface of heavily fed tanks. A clean surface is where your gas exchange takes place. A surface film significantly reduces gas exchange am carrying capacity of a tank.

Aeration is a great way to push the film back and break it up. This method leaves the fat and protein in the tank or splashed at the water line. Surface skimming removes it from the tank completely to be filtered.

For surface skimming to be effective you need thin film of water going over the standpipe. To handle the flow you need the surface area of a larger diameter pipe. A one inch stand pipe can handle the flow rate of this tank but skimming is in effective due to the small cross section of the pipe. With a two inch outer pipe acting as the weir the amount o linear surface area for skimming doubles.

Another key issue for surface skimming to work effectively is the water must drop over the first edge of the skimmer a sufficient
distance so skimmed film doesn't backup on the surface tension stopping the skimming.

Master Piece!

I received an amazing package of TVR goldfish today. They are a little different than the usual fish shipment. These were a gift from Jeff Thompson (Glassgoldfish)  It has University of Oregon yellow and green eyes.

The only other person I know of with one of these is Mr. Oishi, which in and itself is an honor.
